Abstract

The invention discloses a numerical control high-voltage transformer for arc discharge and a control method thereof, the high-voltage transformer comprises a numerical control chip, a current limitingresistor and a switching device connected in sequence, the numerical control chip is connected with a power supply, one end of the current limiting resistor is connected with the output end of the numerical control chip, the other end is connected with the grid of the switching device, the drain of the switching device is connected with one input end of the transformer, the source is connected with the negative pole of the power supply, the other input end of the transformer is connected with the power supply, and the output end is connected with the discharge device. After the arc of the transformer is smoothly started, the numerical control chip performs frequency conversion operation to reduce the power of the high-voltage transformer. The invention fully utilizes the distribution parameters of the transformer, assists the digital frequency conversion control, and solves the problems of high voltage required when striking an arc and power reduction after striking an arc.

Description

technical field [0001] The invention belongs to the technical field of arc discharge high-voltage conversion, and in particular relates to a digitally controlled high-voltage transformer for arc discharge and a control method thereof. Background technique [0002] Arc discharge refers to the gas discharge phenomenon that presents arc-shaped white light and generates high temperature. No matter in thin gas, metal vapor or atmosphere, when the power supply provides enough voltage and current, the gas can be broken down and emit strong light and high temperature. This form of gas self-sustained discharge is arc discharge. Arc discharge is widely used, high power can be used for smelting and welding, medium power can be used for lighting, low power can be used for ignition devices, etc. [0003] The application field involved in the invention is a low-power, continuous arc ignition device, which is mainly used for ignition applications such as kerosene and solid combustibles. ...
